Since 1993, data on Pacific Giant Salamanders has been collected in/along Mack Creek, part of the H.J. Andrews Experimental Forest in Western Cascade Mountains of Oregon. This data collection is part of a larger effort, begun in 1987 to monitor local cutthroat trout populations (2). The H.J. Andrews Experimental Forest is a research site supported jointly by the University of Oregon and the U.S. Forest Service, and funded as part of the National Science Foundation’s Long-Term Ecological Research program (1). Data collection for Pacific Giant Salamanders occurs in two distinct areas, a coniferous old-growth forest and a clear-cut area (c. 1963) (2). Observations gathered pertaining to salamander abundance, weight, type, and location can provide insight as to how the species is affected by factors such as climate change, land use, and other disturbances over time (1).
